Their shipping offer isn’t a gimmick or a bait and switch deal. Sure, there’re some restrictions, like a $125 minimum, shipping weight under 20 pounds, etc. But all the restrictions I read about on the Amazon site were reasonable.
I’m guessing more countries will be added. Everybody loves the word “free” in front of something they want, even if it’s just shipping costs. Commerce is doing its best to build good neighbors through trading.
Our world continues to get smaller by being more intertwined, which is probably good for relations between both people and nations.
